Capsid Nymphs
Juvenile capsid bugs causing distortion, scarring and aborted growth.
Capsid bug nymphs (e.g., Lygocoris spp.) cause significant damage to soft fruit and ornamentals during early growth stages. Nymphs inject enzymes into plant tissue, causing puckering, fruit pitting and distorted growth. They move quickly and hide within foliage. Cultural control includes weed removal and early monitoring. Biological control relies on predatory bugs such as Orius spp. and mirids, though effectiveness varies by crop.
Biological Controls for Capsid Nymphs
The options below are examples of beneficial insects and biological products commonly used against capsid nymphs. Always refer to supplier guidance and product labels for crop safety and local registration status.
Generalist predators (mirids, lacewings)
Product: Macroline (where permitted) + Chrysoline
Environment: outdoor
Temperature Range: 15.0 – 28.0°C
Rate: Field rates per label and crop
Frequency: As dictated by monitoring
Predators may help reduce capsid nymph numbers; often used alongside selective chemistry in soft fruit and ornamentals.
Chrysoperla carnea
Product: Chrysoline
Environment: all
Temperature Range: 12.0 – 30.0°C
Rate: 5–10 larvae per hotspot plant
Frequency: apply to hotspots; repeat as needed
Generalist predator that can help suppress nymph stages when applied early, especially in hotspots.
Adalia bipunctata
Product: Adaline
Environment: all
Temperature Range: 12.0 – 30.0°C
Rate: 2–5/m² depending on pest pressure
Frequency: introduce early; repeat during pressure
Support predator for nymph suppression; best used early with monitoring and cultural control.
